How many people do we need at the cashier?
To be precise, how many people do we need at the end of the cashier?
In Big Bazaar, a large supermarket for middle-class consumers in India. At the end of the cashier found three boys waiting to pack my groceries in a bag. Note that they do not deal with any cash, as there was another lady to take care of that.
How many people do we need to fulfill a task and how are tasks distributed?
